kilp-web@sbcglobal.net Posted April 15, 2010 Share Posted April 15, 2010 I have been experimenting with the following code: <html><head><title>List the Tags</title><script type="text/javascript">function listTags(n, i) { ++i; // Loop through all the children of n for(var m = n.firstChild; m !== null; m = m.nextSibling) { alert(i); if (m.nodeType === 3) { // Text Node if (m.nodeValue === "\n") { alert(m.parentNode.nodeName + " " + m.nodeName + " " + m.firstChild + "\n" + " nodeValue is 'linefeed'"); } else { alert(m.parentNode.nodeName + " " + m.nodeName + " " + m.firstChild + "\n" + " nodeValue is: " + m.nodeValue); } } else { alert(m.parentNode.nodeName + " " + m.nodeName + " " + m.firstChild.nodeName); } listTags(m, i); }}</script></head><body onload="listTags(document,0);"><button onclick="bounce.start()">Start</button><button onclick="bounce.stop()">Stop</button></body></html> When I run this it shows that there are a lot of unexpected (by me at least) #text nodes whose nodeValue is "\n".Is there a bug in my code or are these real? If they are real, what purpose do they serve?I have run this on both Safari and Firefox with the same results.Thanks,Jerry Link to comment Share on other sites More sharing options...
jeffman Posted April 15, 2010 Share Posted April 15, 2010 That symbol indicates a new line. You are examining all the lines in your document. Everywhere a new line begins, there must be a text node with a new line character. Sometimes it is the only character. Sometimes it may be combined with tabs or spaces.Their purpose is to make your page look readable. Those are the places where you hit the return key.
